Need Help for some modification

New comment

Hello.. am creating an EA based on a custom indicator... the problem is filtering the buy and sell signal

after creating the EA to open buy on buffer ''0'' and sell on buffer '1' but the EA will open only sell orders on a buy/sell signal (all signals)

after trying some modifications for 2 days, and some help from some programmers it will open both a buy and sell at once

am sure the problem is from the indicator coding

suggest sell buffer coding separately and buy buffer coding separately

Thanks



SetIndexBuffer(0,histou);SetIndexStyle(0,ShowBars ? DRAW_HISTOGRAM : DRAW_NONE); 
   SetIndexBuffer(1,histod);SetIndexStyle(1,ShowBars ? DRAW_HISTOGRAM : DRAW_NONE);

Abubakar Saidu: after creating the EA to open buy on buffer ''0'' and sell on buffer '1'
  1. Why did you post your MT4 question in the Root / MT5 EA section instead of the MQL4 section, (bottom of the Root page?)
              General rules and best pratices of the Forum. - General - MQL5 programming forum
    Next time post in the correct place. The moderators will likely move this thread there soon. 
  2. if (_startTime<= Time[i] && _endTime>=Time[i])
    Note: your inputs are 0:00 … 3:59 and with the equals your code runs from 0:00:00 … 3:59:00. It does not run on the last minute. By dropping the trailing equals and using 04:00, your code will run from 0:00:00 … 3:59:59 which is what you really want. 
  3.          if (_startTime<=Time[i] && _endTime>=Time[i])
        { 
            fillu[i]  = max;            
            filld[i]  = min;
            histou[i] = EMPTY_VALUE;
            histod[i] = EMPTY_VALUE;
    During your proper times you don't fill in buffers 0/1.
               if (histoc[i] == 1) { histou[i] = High[i]; histod[i] = Low[i]; }
            if (histoc[i] ==-1) { histod[i] = High[i]; histou[i] = Low[i]; }
    Outside of those times you do fill in the historgrams (blue or yellow.)

Thanks for your reply will be careful..

i still don't understand 
histou[i] = EMPTY_VALUE;
histod[i] = EMPTY_VALUE;

i changed the EMPTY_VALUE to Buffer_0/Buffer_1

but still nothing but an ERROR

can you please solve it and reply the right code

this is the mt5 indicator... it was converted to mq4
